If you're here in the USA you're going to have a hard time finding someone that is going to be willing to take you on as a Wiccan student..at least you'd have a hard time finding anyone reputable that would do it. This is because it is against the law to interfere in the religious upbringing of a minor without the consent of their parents. And Wicca is very much a religion. That's why you are unlikely to find a teacher or a coven that will accept you until you are at least 18 years old.
You might want to take a look at some of the resources that I provided at http://www.spellsofmagic.com/read_post.html?post=219447 And of course if you have specific questions you can always post them to the Wiccan forum here and people will try to answer you.
Be very cautious in finding a teacher on the internet. Not everyone who hangs out on these boards is a friend. It is not uncommon for sexual predators to cruise such forums looking to connect with people just like yourself by saying that they will be your teacher. Never agree to meet with someone in person without having someone else you trust with you. Always be safe.
